Alleviation Of Nacl Stress In Summer Squash ‘Eskandrani’ By Foliar Application Of Salicylic Acid

Abstract

The experiment was performed to assess the possibility of overcoming NaCl salinity stress by foliar sprays of summer squash ‘Eskandrani’ with salicylic acid (SA) at the concentration of 10-6 M. NaCl treatment caused reduction of shoot fresh weight, leaf number per plant, fruit yield, concentrations of potassium in aerial parts, and the concentration of chlorophyll in leaves. Plants grown under salt stress conditions had higher shoot sodium concentrations than plants untreated with NaCl. Foliar application of SA ameliorated partly the negative effect of NaCl treatment. The beneficial effect of SA was also observed in non-stressed plants, increasing the shoot potassium accumulation and leaf photosynthetic pigments status, and decreasing sodium accumulation in shoots.

Augmenting the Tolerance Potential of Muskmelon (Cucumis melo L.) Using Salicylic Acid

“…Our results showed that exogenous SA had a positive effect on muskmelon growth and tempted salinity stress for it. Exogenous SA significantly improved all the vegetative growth attributes both in normal and saline conditions and these findings are in Ibrarullah et al accordance of previous reports (Elwan and EL-Shatoury, 2014;Noreen and Ashraf, 2008), who acquired greater biomass for sunflower and cabbage plants both in saline and non-saline conditions when treated with SA. Bayat et al (2012) described that exogenous SA increased shoot and root dry weight, leaf areas and plant heights of calendula under salinity stress conditions.…”

“…Numerous studies describe the productive role of SA in plants under salt stress conditions (Yadu et al, 2017;Tufail et al, 2013). Exogenous SA has the feature to reduce toxic ions (Na + ) accretion in shoot and leaf and increase ratio of beneficial ions such as K + and Ca 2+ in saline conditions (Elwan and El-Shatoury, 2014). In addition to this, SA fastens the uptake of other plant beneficial elements such as Mn, Ca, Cu, Fe, P and Zn and thereby reduces oxidative stress (Wang et al, 2011).…”

Exogenous Application of Ascorbic Acid to Induce Tolerance Against Salt Stress in Common Bean Plants

“…Afterwards, seedlings were irrigated with ddH 2 O containing 0 (control), 50, 100 and 150 mM NaCl. While half of the plants were sprayed with 3 mM AsA (Elwan et al, 2012;Ergin et al, 2014) every three days for 2 weeks (5 applications) in order to investigate whether AsA was effective on salt tolerance of the genotypes, the other half were used as control plants. The amount of water to be given was determined by the pot tensiometer (Irrometer, Co. Riverside, Calif, USA).…”

Synergistic Interactions of Arbuscular Mycorrhizal Fungi and Salicylic Acid Alleviate Adverse Effects of Water Salinity on Growth and Productivity of Watermelon via Enhanced Physiological and Biochemical Responses

“…In addition, exogenous application of salicylic acid induces the antioxidant enzymes activity and subsequently augments plant resistance to NaCl toxicity (He and Zhu 2008). The ameliorative effects of foliar application of salicylic acid have been reported in inducing salt tolerance in some cucurbits such as cucumber (Yildirim et al, 2008, Dong et al, 2011and Youssef et al, 2018, summer squash (Elwan and El-Shatoury 2014), melon (Nasrabadi and Saberali 2020) and watermelon (Ayyub et al, 2015 andRibeiro et al, 2020).…”
